Re: Projectile Motion



I think that is what I said in my first reply, however when it comes to
testing problem solving--and problem solving is a very legitimate goal of an
intro-physics course--then I would apply my advice about 'cheat sheets'. I
both quiz and test. Labs and quizzes on the conceptual, homework and tests
on the problem solving. Both conceptual and problem solving on the final.
Of course, problems also have a strong conceptual component, but often
difficult for us to separate student trouble with problem solving from that
with concepts. Hence the two assessment modes help both the student and the
instructor to keep track of progress.

I agree with Jim (for once) and disagree with Rick. You want to teach
concepts, so discuss concepts, demonstrate concepts, ask about concepts.
The math stuff comes later because otherwise it is a complete distraction.

In other words, spend classtime developing the knowledge that you want to
see in test answers.
